I was thinking about this today about how after trying everything under the sun there are just some pedals I always come back to. So my question to you is what are your best of the best pedals? For me they are:

Devi SPAEDwarfcraft TGDFuzzhugger AB-SynthIbanez Standard Fuzzhaven't since left the pedalboard

and I seem to return to use these, though they have left the pedalboard at least once Schaller FuzzSnarling Dogs Mold Spore WahMarshall Guv'nor.

Marshall Guv'nor must be my #1 most used pedal. Without even any bass mods. Haven't had one for a few years now and I still think I might get one. I have grown to like it so much I always do. Two have been stolen from gig, so the live sounds can't have sucked.

Ampeg Scrambler of one type or another (have had original, RI, and several clones go through, I kept two particularly mean clones)Fender Blender (RI is fine, I just deal with the volume drop)Digitech Time BenderReal tape Space Echo (ok, so it's a suitcase, not a pedal, but...)Boss GL-100 (rackmount, but it has a pedal attached!)Digitech RDS series LFO-freakout delays (rackmount, but has pedals attached again)

And a bit weirdly since I no longer have it, TAFM. I only got rid of it to try out other stuff, because I play guitar more and can't afford to have that many pedals, it's the best bass fuzz there is imo.
